Application

The Roller Swage OR is designed to restore internal diameter of damaged casing pipes by means of rolling-off during repair-and-renewal operations in the well.

Design

The Roller Swage OR consists of body made of alloy steel, three rollers and tail piece. There is a box connection tool-joint thread at the top. The middle part has rotating rollers which are set on three eccentric grooves located at 120˚ angle. Rollers are set on the body by rotary tail piece which is fixed by balls located in grooves of body and tail piece. Balls are fixed in grooves by thread plug.
Sets of rollers have different diameter. They are chosen depending on required diameter of swage and internal diameter of casing pipe.
There are slots on surface of eccentric guide grooves, which are filled with graphite grease.
Construction of the Roller Swage provides usage of same body after changing rollers to straighten casing pipes with same nominal diameter but with different internal diameter (with different well thickness). Each nominal size of the roller fits its own outer diameter of tail piece.
